The transient absorption spectrum of o-iodobenzoyloxyl radicals was observed for the first time in acetonitrile using 1-(o-iodobenzoyloxy)-2-pyridone as a precursor. On the basis of the comparison of the spectra of o-halobenzoyloxyl radicals, it is proposed that the o-iodobenzoyloxyl radicals take a planar structure with a strong interaction between the radical center oxygen atom and the neighboring
以1-(邻碘苯甲酰氧基)-2-吡啶酮为前驱体,首次在乙腈中观察到邻碘苯甲酰氧基自由基的瞬态吸收光谱。通过对邻卤苯甲酰氧基自由基光谱的比较,提出邻碘苯甲酰氧基自由基呈平面结构,自由基中心氧原子与相邻的碘原子之间具有强相互作用。
